A seat assembly is provided for supporting in an automotive vehicle. The seat assembly comprises a seat cushion and a seat back pivotally coupled to the seat cushion for movement between a reclined seating position and a fold flat position. A recliner assembly is coupled between the seat back and the seat cushion to provide pivotal movement of the seat back. A riser assembly is pivotally coupled to the seat cushion and pivotally latched to the floor to allow pivotal movement of the seat cushion between a horizontal seating position and a forwardly upright tumbled position. A release mechanism is coupled between the seat back and the riser assembly for automatically synchronizing actuation of the recliner assembly and the riser assembly to provide movement of the seat assembly to the tumbled position in response to the pivotal movement of the seat back to the fold flat position.

A release mechanism selectively actuates a recliner between a locked condition and an unlocked condition allowing pivotal movement of a seat back between a seating and fold flat position. The release mechanism includes a recliner cam lever operatively coupled to the recliner for actuating the recliner between the locked and unlocked conditions. A recliner handle lever engages the recliner cam lever in a first actuated position to actuate the recliner between the locked and unlocked conditions allowing pivotal movement of the seat back between a seating position and a fold flat position and further engages the recliner cam lever in a second actuated position to release a seat cushion from the floor and allow pivotal movement of the seat cushion between a seating position and tumbled position when the seat back is maintained in the fold flat position.

Fold and tumble release mechanism

A seat track assembly includes a seat track operable for sliding movement of a seat assembly. A towel bar pivots a drive lever unlocking the seat track and allowing sliding movement of the seat assembly within a range of comfort positions. A stop lever pivots between a lowered position and a raised position. In the lowered position, the stop lever engages a stop bracket secured to the seat track preventing the seat assembly from moving forward of the range of comfort positions. A cam pivots in response to pivotally moving a seat back to a dump position. Pivoting the cam pivots the drive lever unlocking the seat track and pivots the stop lever to the raised position spaced above the stop bracket to allow sliding movement of the seat assembly to an easy-entry position forward of the range of comfort positions.

Seat track easy-entry actuation mechanism

A seat assembly has a seat cushion pivotally supported by a pair of front support links for movement between a seating position for supporting a seat occupant and a stowed position. A seat back is pivotally supported by a pair of recliner mechanism for movement between an upright position and a stowed position. The seat cushion moves from the seating position to the stowed position in response to pivotal movement of the seat back from the upright position to the stowed position. A J-link extends between the seat back and the front support links. A torsion spring biases the seat cushion to the stowed position. A control cable operatively couples the seat back and the seat cushion. A pair of support legs automatically deploy as the seat cushion rotates to the stowed position.

Fold flat seat assembly

The seat assembly comprises a seat cushion () and a seat back (). A recliner assembly () operatively interconnects the seat cushion and the seat back for selective locking and adjustment of the seat back between a plurality of reclined seating positions (B) and a stowed position (D). A stop () is pivotally mounted to the seat cushion for movement between first and second positions. The stop includes a hook () presented for engagement with the seat back when the stop is in the second position for maintaining the seat back in a tilted position (G) between the plurality of reclined seating positions (B) and the stowed position (D). When the stop () is in the first position, the seat back may be adjusted between the plurality of reclined seating positions (B. A track assembly () extends between the seat assembly and the vehicle for selective locking and adjustment of the seat assembly within vehicle between a plurality of fore and aft seating positions (E) and an easy entry position (F) forward of the seating positions (E). The stop () is operatively interconnected () to the track assembly () for locking and unlocking the track assembly during rotation of the stop () between the first and second positions, respectively.

Tip easy entry and fold flat recliner assembly

A seat assembly comprising a seat cushion, a seat back and a recliner assembly operatively interconnecting the seat back to the seat cushion. The recliner assembly allows pivotal adjustment of the seat back relative to the seat cushion between one of a plurality of reclined seating positions and a stowed position. The recliner assembly is selectively moveable between locked and unlocked states. An input shaft is operatively assembled to the recliner assembly for switching the recliner assembly between the locked and unlocked states. The seat assembly further comprising a mechanism externally engagable with the input shaft of the recliner assembly for adjusting the angular position of the seat back in one of the reclined seating positions and for maintaining the input shaft in the unlocked position while the seat back is pivoted from one of the reclined seating positions to the stowed position. First and second levers are pivotally mounted to the seat cushion and moveable between unreleased and released positions. A guide pin extends from the first lever through a slot in the second lever to synchronize movements of the first and second levers between respective unreleased and released positions. The second lever includes a cam surface for actuating the input shaft between the locked position and unlocked positions when the second lever is moved between the unreleased and released positions, respectively. The second lever further has a flanged tab. A flanged guide extends from the seat back to engage the tab of the second lever in the released position, and by such engagement, maintains the second lever in the released position while moving the seat back between the reclined seating positions and the stowed position.

External control of recliner assembly background of the invention

A seat cushion assembly includes a seat cushion frame operatively coupled to a seat track assembly by a seat cushion height adjuster for selectively positioning the seat cushion frame between a raised position and a lowered position. The seat cushion height adjuster includes front pivot shaft and rear pivot shaft journaled to the seat track assembly. A front pair of pivot links pivotally interconnect the seat cushion frame to the front pivot shaft and a rear pair of pivot links pivotally interconnect the seat cushion frame to the rear pivot shaft. A horizontal link interconnects each of the pairs of front and rear pivot links for synchronized movement. The adjuster further includes a powered drive assembly having a motor and gear box supported by a motor bracket between the front and rear pivot shafts for driving a screw shaft. A screw nut is threadedly coupled to the screw shaft for movement therealong. A torque bracket is coupled between the screw nut and the rear pivot shaft for rotating the rear screw shaft. When the screw shaft is rotated by the motor, the screw nut travel along the shaft and rotates the torque bracket and rear pivot shaft. The rear pivot shaft rotates the rear pivot links about an arcuate path to raise or lower the rear of the seat cushion frame. The horizontal links rotate the front pivot links about an arcuate path to simultaneously raise or lower front of the seat cushion frame.
